How would use a similar chemical shorthand to write a representation of the molecules of iodine and fluorine

Explanation:

Chemical shorthands are simply chemical symbols which are derieved from the English or latin or Greek names of elements. For example, in writing a chemical reaction, instead of writing the element iron, we simply write Fe which is shorthand form.

For the molecules of Iodine:

  Iodine is in the halogen group on the periodic table. It's shorthand form is designated as I . A molecule of Iodine is written as I₂.

For the molecules of fluorine:

 Fluorine is also an halogen. It is represented by the symbol F. A molecule of fluorine is written as F₂.

qualitative observation deals with data that can be observed with our senses: sight, smell, touch, taste, and hearing. they do not involve measurements or numbers. for instance, colors, shapes, and textures of objects are all qualitative observations.
